Gelatins of three densities are poured into a large pan. Gelatin I is a diluted and soft gelatin, Gelatin II is a regular, firm gelatin, and Gelatin III is an extra firm, rubbery gelatin. A pulse in the shape of a trough is generated in 1. A pulse ( wavelength) is generated that extends exactly 1 color-band, that is, over 1 section of gelatin. In other words, the first pulse generated extends from the front end of the pan to the blue/red boundary. Choose whether the pulse will transmit as a trough or a crest under the following conditions.

At boundary A, the transmitted pulse will be a
.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Amagnetic field applies forces on: a)static chargesb)moving chargesc)water flow

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?
